as though it possessed no self-induction

l have found that in every coil there exists a certain relation between its self-induction and capacity that permits a current of given frequency and potential to pass through it with no other opposition than that of ohmic resistance, or, in other words, as though it possessed no self-induction.

Many long nights as a child were spent fishing for interesting sounds and stations on my AM radio.  I heard KDKA, the world’s oldest commercial radio station, the BBC from London, and on rare days, a station from South Africa.  But the most interesting experiences came from those areas on the dial that had a tremendous amount of interference, when I tuned the radio to whistles, pops, beeps, and static.
